Red Hat: The hypervisor will be free
,----[ Quote ]
| Red Hat has predicted that virtualisation will be included in all operating
| systems for free, while setting out the roles of the two hypervisors it is
| working on for its own product range.

Red Hat sprints past ESX on VM running
,----[ Quote ]
| Red Hat claims it can run five virtual machines (VMs) for every three that
| VMware's ESX runs in the same server hardware. Qumranet technology also
| enables it to run more Windows virtual desktops than VMware, too.
|
| At a journalists' roundtable in London this week, Benny Schneider, Qumranet
| CEO, said his - now Red Hat's - company's KVM (kernel-based virtualisation
| machine) hypervisor runs 52 VMs in a physical server, in which ESX can host a
| maximum of 35 VMs. Citrix Xenserver is worse: it can only host 30.

Hypervisor Visionary

| Benny Schnaider is a man who figures to have some influence in how
| competition in the virtualization market plays out. Schnaider is the CEO and
| co-founder of Sunnyvale, Ca.-based Qumranet Inc., which is the sponsor of the
| Kernel-based Virtual Machine (KVM) technology. KVM is an open source
| alternative to the Xen hypervisor, which recently became an approved
| component of the Linux kernel.

| Endorsed by Red Hat Inc. and Canonical Ltd.'s Ubuntu -- as well as supported
| in hardware by Intel Corp., Advanced Micro Devices Inc. and IBM Corp. -- KVM

Ubuntu 8.04 KVM Benchmarks

| With these few single threaded tests, the results were very close between

| by KVM. In fact, to an end-user, the results between the two environments
| wouldn't even be noticeable.

Ubuntu picks KVM over Xen for virtualization
,----[ Quote ]
| KVM will be built into Ubuntu's next version, called Hardy Heron and due in
| April. "For the Hardy Heron release, we've really picked up the
| virtualization ball. Virtualization is making its way into data centers and
| onto developer workstations everywhere. Even 'regular' users are using it to
| run Ubuntu on Mac OS X all the time," Hansen said. "Virtualization has been
| on our agenda for a long time, but it became a top priority at UDS (Ubuntu
| Developer Summit) in November. We could see that demand for it was growing."

The truth about KVM and Xen
,----[ Quote ]
| When the distros first shipped Xen, it was done mostly out of desperation.
| Virtualization was, and still is, the "hot" thing. Linux did not provide any
| native hypervisor capability. Most Linux developers didn't even really know
| that much about virtualization. Xen was a pretty easy to use purpose-built
| kernel that had a pretty good community. So we made the hasty decision to
| ship Xen instead of investing in making Linux a proper hypervisor.
|
| This decision has come back to haunt us now in the form of massive confusion.
| When people talk about Xen not being merged into Linux, I don't think they
| realize that Xen will never be merged into Linux. Xen will always be a
| separate, purpose-built kernel. There are patches to Linux that enable it to
| run well as a guest under Xen. These patches are likely to be merged in the
| future, but Xen will never been a part of the Linux kernel.
|
| [...]
|
| Looking at the rest of the industry, I'm surprised that other kernels haven't
| gone in the direction of Linux in terms of adding hypervisor support directly
| to the kernel.
|
| Why is Windows not good enough to act a hypervisor such that Microsoft had to
| write a new kernel from scratch (Hyper-V)?
|
| Why is Solaris not good enough to act as a hypervisor requiring Sun to ship
| Xen in xVM? Solaris is good enough to run enterprise workloads but not good
| enough to run a Windows VM? Really? Maybe :-)
|
| Forget about all of the "true hypervisor" FUD you may read. The real question
| to ask yourself is what is so wrong with these other kernels that they aren't
| capable of running virtual machines well and instead have to rely on a
| relatively young and untested microkernel to do their heavy lifting?
